PyInstaller不包含依赖文件

Question

我正在尝试在我的project中创建一个使用PyInstaller。

这个项目使用weasyprint，但是当我运行pyinstaller时，它失败了，因为weasyprint的资源文件似乎没有被安装。

有没有办法强制pyinstaller包括这个文件？

我可以自己加一下吗？

命令：pyinstaller mainwindow.spec

mainwindow.spec：

# -*- mode: python -*-
a = Analysis(['mdedit/mainwindow.py'],
             pathex=['/home/sylvain/git/md-edit'],
             hiddenimports=[],
             hookspath=None,
             runtime_hooks=None)
pyz = PYZ(a.pure)
exe = EXE(pyz,
          a.scripts,
          exclude_binaries=True,
          name='mainwindow',
          debug=False,
          strip=None,
          upx=True,
          console=True )
coll = COLLECT(exe,
               a.binaries,
               a.zipfiles,
               a.datas,
               strip=None,
               upx=True,
               name='MdEditor')

提前致谢。

我有一个类似的问题，可能是同一个问题，并按如下方式解决。希望这对你有用：

# -*- mode: python -*-

from PyInstaller.utils.hooks import collect_data_files

w = collect_data_files('weasyprint')
ww = []
for k,v in w:
    ww.append((k, v.split('weasyprint/')[1]))
added_files += ww
added_files += collect_data_files('pyphen')
extra_imports = ['pyphen', 'weasyprint']

a = Analysis(['mdedit/mainwindow.py'],
             pathex=['/home/sylvain/git/md-edit'],
             datas=added_files,
             hiddenimports=extra_imports,
             hiddenimports=[],
             hookspath=None,
             runtime_hooks=None)
pyz = PYZ(a.pure)
exe = EXE(pyz,
          a.scripts,
          exclude_binaries=True,
          name='mainwindow',
          debug=False,
          strip=None,
          upx=True,
          console=True )
coll = COLLECT(exe,
               a.binaries,
               a.zipfiles,
               a.datas,
               strip=None,
               upx=True,
               name='MdEditor')

我在weasyprint面临着类似的问题，并且能够使用@Schwolop的答案进行一些修改，因为我收到'tinycss2'的错误。这是我的spec文件的第一部分：

w = collect_data_files('weasyprint')
tinycss = collect_data_files('tinycss2')

ww = []
counter = 0
for k,v in w:
    if counter == 0:
        ww.append((k, '.'))
        counter += 1
    else:
        ww.append((k, v.split('weasyprint/')[1]))

tcss = []
counter = 0
for k,v in tinycss:
    if counter == 0:
        tcss.append((k, '.'))
        counter += 1
    else:
        tcss.append((k, v.split('tinycss2/')[1]))

added_files = ww
added_files += collect_data_files('tinycss2')
added_files += collect_data_files('cairocffi')
added_files += collect_data_files('pyphen')
added_files.extend(more_data)
extra_imports = ['tinycss2', 'cairocffi', 'pyphen', 'weasyprint']
